Synchronisation in id3

Question

I am not clear about synchronisation and unsynchronisation in id3 tags.

I have read the developer info, but i could not able to understand.

Can you please help me in explaining the things clearly.

Thanks.

Answer 1

What more precisely you do not understand? It seems documentation is quite clear. The synchronisation can be used to some (in general legasy) programs, that do not know about ID3v2, does not accept tag data as frame header. By the way, it seems majority of programs does not use syncronisation, and possible if you faced with dificulties with synchronisation you can try do not work with synchronized tags.

Answer 2

I have tried to explain the unsynchronization scheme in a writeup here. In addition to the specifications you might want to have a look at http://phoxis.org/2010/05/08/what-are-id3-tags-all-about/#unsyncsafe
